Bonnin nacre Application ed october 12,-1925. Serial Ko. 62,082.

This invention relates to an improved .rack which is especially, although not necessarily, designed for supportin and maintaining thread bobbins in an'or erly fashion for convenient4 use, the same being particularly useful-in association with a hem stitching-machine.

My :principal object. is lto generally improve upon devicesof this kind by providing one of comparative simplicity and durability wherein the details are such and'so f arranged as to permit employment of a comparatively small structure for accommodatiner a multiplicity of bobbins.

2More particularly, I propose a rack of stepped formation wherein the horizont-al shelf-like portions are provided with upstanding longitudinally spaced pins each of which is of a length and size to accommodate a pair of conventional bobbins, whereby to permit a pair with the same color and shade of thread or silk to be arranged in a manner to facilitate selection and use.

Other objects and advantages will become .apparent from the following description and drawings.

In the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same Figure 1 is a front elevation of va .bobbin rack constructed in accordance with the present invention,

Fig. 2 is a central vert-ical section through the same,

Fig. 3 is a fragmentary detail view showing the approximate manner in which a pair of bobbins are racked.

.- Referring to the drawings in detail, it

will' be seenthat the 'entire device is made from sheet metal and is composed in the main of 'three separate sheets. One sheet comprises lthe base 1, the back 2, and the front 3.' The sheet is bent upwardly as at 4 in forming the back wall, is bent upon f. itself as at' 5 and 'downwardly as at 6 in 'forming-the' front. This front is of stepped configuration f and includes horizontal shelves or rests 7 and vertical connections 8. The end of the/sheet is bent upon itself upon its free end as indicated at 9 to form a reinforcing fiange and itwill be noted that this flange is disposed'above the` bottom and terminates inwardly pf the same in order to accommodate al slidingjdrawer 10 provided/'with ajkllbdll.

In order to close the opposite ends and to make for rigidity of structure, a pairof duplicate side plates 12 are employed.

These side plates resemble bridge boards of r a stair structure in side elevation and they thereby accommodate the stepped formation of the front 3. The bobbin pins 13 may in the form of rivets or the like, these being fastened to the horizontal shelves 7 at be -v equally spaced points in order to .-.accommodate the bobbinsl 14.-. As previously stated, each pin will be of a length and slze to accommodate a pair of bobbins( As Dis `well known, the bobbins are ordinarily used m pairs and each pair has the same' color and shade of silk wound thereon.

Obviously, the convenience of maintain-l ing the same in pairs for rapid use is quite evident. In connection with the stepped front formation, and the correspondingly shaped edge of the side plates, 1tl will be noted that. the sideplates are formed with tongues 15 and these areextended through slits in the vertical part 8 and then bent sembled.

The connection between the other edges of the'side-plates and the back and bottom walls may be obtained .in any appropriate manner such as by soldering or an other form of connection. The outstandlng advantage of a device of this kind is that it ,requires but very little space and may be fourteen device over as shown to maintain the front asei ht and considera ly less in uio rack andpick out the desired colors in a few moments.

' It is believed that by considering the description in connection with the drawings, persons familiar with inventions of this class will be able to obtain a clear understanding of the same.` Therefore a increV lentil description is thought unnecessary.

e the invention has een shown and described, it

referred embodiment of theis to be understood that minor changes coming within the iield of invention claimed may be resorted to if desired.

Having thus described my invention, what A bobbin holder of the class described comprising a sheet of metal bent uponv itself to form a base, an upstanding rear wall and a. downwardly and forwardly inclined front, said front being bent at longitudinally spaced points to form a plurality of stepped formation, the lowermost horizontal portion terminating above and being spaced inwardly from the adjacent end 'of said maaier base, side plates connected withthe front, 15 rear wall and base, the upper edges of said plates being notched to accommodate the steps of the front, said vertical portions of the steps being formed with openings and said side plates being provided with ton es 20 extending through said openings and ent upon themselves to hold the side' plates in place, and a plurality of bobbin supporting .pins carried by the horizontal portions of the steps.

In testimony whereof I affix my signature.

JAMES N. HARROI).
